WATER-P'URIFIER.

Application filed March 30, 1903. Serial no. 150,255. (No model.)

To all whom it may concern.-

Be it known that I, CASS L. KENNIOOTT, a citizen of the United States, residing at Chi-' cago, in the county of Cook and State of Illinois, have invented a new and useful Irnprovement in Water-Purifiers, of which thefollowing is a specification.

My invention relates to an improvementin the class of apparatus for treating water used for industrial purposes by means of 'chem' icals to relieve it of its contained substances that tend to render it injurious to the mechanism with which it is employed, as by forming scale on the surfaces of boilers in which steam is generated.

More particularly stated, my invention relates to the part of such a water-purifying apparatus which forms an attachment for antomatically supplying the chemical solution in predetermined proportion to the water to be treated with it; and it relates especially to an improved construction of the form of attachment for the purpose stated involving a tilting receptacle into which the'water to be treated is caused to flow and to rock the receptacle for the twofold purpose of emptyvention in its preferred form as to details,

illustrated in the accompanying drawings, in which- 7 V Figure 1 is a plan view of my improved device; Fig. 2,.a section taken at the line 2 on Fig. 1 and viewed in the direction of the arrow; Fig. 3, a section taken at the line 3 on Fig. l andviewed in the direction of the arrow, and Fig. 4: an enlarged perspective view of a cup in detail.

A is a holder for the chemical solution to be used for treating the water to be purified, audit may be connected for its supply with a chemicalmixing tank, (not shown,) such as is commonly provided in apparatus of the class to which my improvement relates. holder is shown in its preferred form of a semicylinder. In the opposite sides of the holder is journaled a rock-shaft B, carrying between its ends within the holder one or 'more stirring arms or paddles a and rigid arms I) and 2), extending in opposite directions toward the ends of the holder, adjacent to which on their extremities they carry pivotally cups 0 and 0, preferably, though not necessarily, of the flaring shape illustrated, and a semicircular rib O is shown projecting centrally from the inner surface of the base of the holder and extending at its extremities to openings (shown as rectangular recesses c and c) in the opposite ends of the holder to afford a guide-bearing for the cups. Adjacent to one side of the holder is supported the tilting receptacle D, represented in its preferred scoop form with an upright partition 01 centrally between its ends, dividingit into compartments D and D At its transverse center the receptacle D is secured at its base to a shaft 6, journaled to extend parallel with the shaft B and to rock in bearings at its opposite ends, and the receptacle is flexibly connected from a side of one of its compartments with the shaft B, as through the medium of a link f, adjustably fastened to a crank-arm f on one end of that shaft. Similar conduits or gutters E E, rep.- resented as covered at their inlet ends, are shown to lead, respectively, from the recesses c and c to the receptacle-compartments D andD The operation is as follows: The water to be treated is caused to flow into the receptacle D, as from a supply-pipe F, discharging downward into it near its center. As one of the compartments-saythe compartmentD fills with water the weight rocks the receptacle accordingly on the shaft e, causing it to discharge the contents of the compartment into a suitable receiver (not shown) for the treated water. In thus rocking, the receptacle, through its connections f and f with the The ed to hold. In thus rising the cup 0 scoops itself full of the chemical solution in the holder, and on entering the opening cit turns on its pivot over the base of the latter and discharges its contents into the conduit E,

whence the solution runs into the compartment D of the receptacle before any or much water to be treated enters the same. As the compartment D in the tilting of the receptacle D empties itself of its contents the compartment D comes beneath the supply-pipe F, from which it is filled with the water, and the weight thereof rocks the receptacle in the opposite direction to discharge the contents of the last-filled compartment, thereby swinging the paddles in the direction contrary to that already described, and the arm I) correspondingly to raise the adjacent cup 0 along the bearing O and causeit to tip overthe base of the adjacent opening 0' to discharge the contents it has been caused to scoop up from the holder B into the conduit E for i11- troduction into the compartment D of the tilting receptacle then in position to be filled from the pipe F. In this manner the receptacle is rocked back and forth to fill and discharge the contents of its compartments successively and to actuate the cups to charge each compartment before it becomes filled with the water to be treated with the predetermined proper proportion of the chemical solution for treating it.

As will be understood, the relative capacities of the cups and the compartments of the tilting receptacle may be varied according to the particular requirement of the relative proportions of the chemical solution and water,and while the construction of myimproved attachment is the bestnow known to me, it may be variously modified by those skilled in the art without departure from myinvention.

What I claim as new, and desire to secure by Letters Patent, is

1. An attachment fora water-purifier, comprising, in combination, a chemical-solution holder provided with a rockshaft carrying cups, and a tilting receptacle supported adjacent to said holder, divided into compartments and connected with said shaft to rock the latter by the weight of the contents of the compartments and actuate the cups, substantially as described.

2. An attachment for a water-purifier, comprising, in combination, a chemical-solution holder provided with a rock-shaft carrying cups and a stirrer, and a tilting receptacle supported adjacent to said holder, divided into compartments and connected with said shaft to rock the latter by the weight of the contents of the compartments and actuate the cups and stirrer.

3. An attachment for a water-purifier, comprising, in combination, a chemical-solution holder, a rock-shaft journaled on said holder, arms extending from said rock-shaft toward the opposite ends of the holder, cups pivoted on the ends of said arms, conduits on said holder, into which said cups discharge, and a tilting receptacle supported adjacent to said'holder to receive the discharge from said conduits, and divided into compartments and connected with said shaft to rock the latter by the weight of the contents of the compartments and actuate the cups, substantially as described.

4. An attachment fora water-purifier, comprising, in combination, a chemical-solution holder, a rock-shaft journaled on said holder and carrying therein a stirrer, arms extending from said rock-shaft toward the opposite ends of the holder, cups pivoted on the ends of said arms, conduits on said holder into which said cups discharge, and a tilting receptacle supported adjacent to said holder to receive the discharge from said conduits, and divided into compartments and connected with said shaft to rock the latter by the weight of the contents of the compartments and actuate said cups and stirrer, substantially as described.

5. An attachment for a water-purifier, comprising, in combination, a chemical-solution holder having openings in its opposite ends and a cup-guide extending on its base between said openings, a rock-shaft journaled on said holder, arms extending in opposite directions from said rock-shaft toward said openings, cups pivoted on the ends of said arms, a tilting receptacle supported adjacent to said holder, divided into compartments and connected with said shaft to rock it by the weight of the contents of the compartments and actuate the cups, and conduits leading from said openings to the receptaclecompartments, substantially as described.

6. An attachment for a water-purifier, com-- prising, in combination, a chemical-solution holder having openings in its opposite ends and a cup-guide extending on its base between said openings, a rock-shaft journaled on said holder and carrying stirrer-arms embracing said guide, arms extending in opposite directions from said rock-shaft toward said openings, cups pivoted on the ends of said arms, a tilting receptacle supported adjacent to said holder, divided into compartments and connected with said shaft to rock it by the Weight of the contents of the compartments and actuate the cups and stirrerarms, and conduits leading from said openings to the receptacle-compartments, substantially as described.
